v The machine comprises a suitable framework for supporting the operating parts, said frame-work embod 'ng standards -1 and connecting pieces 2. drive-shaft 3 is mounted Specification a: Letters Patent. Application filed m 1.1907. Serial No. 372.860;

Patented 17', 11907 and is a apted to be intermittently driven being thrown into gear'by a suitable startin mechanism and automatically thrown out 0 gear at each complete revolution. A drive pulley 4.- is loose upon the drive shaft and is adapted to be-continuously driven from a suitable source of ower. A sleeve 5 is keyed to the drive s aft and is adapted to make clutched engagement with the drive pulle and to be automatically thrown out of clutc ed enga ement at each complete revolution of the rive shaft. The drive shaft is thrown into gear for starting the machine by means of a treadle'mechanism which embodies a shaft 6, treadle 7, crank 8 and connection 9, the latter engaging with the clutch sleeve 5 to eifpct movement thereof to throw the same into engagement with the drive pulley upon operating the treadle 7. Cams 10,11, 12 and 13 are fast. to the drive shaft 3 so as. to rotate therewith and each performs a special office in the operation of the machine as will be apparent from the subjoined description.

frame 14 is mounted to swing and nor- Inally position an upper end and is lower end. or near its ends near the lower ends of the standards 1 and receives the frame .14 which is mounted thereon and secured in an ad justed A portion of the frame 14 and the jaws are mounted thereon. The jaws are of similar formation and frames 18 and levers 19, the latter being by preference bolted to the frames and arran ed so as to clear each other and avoid inte ence with the respective cams 11 and 12. The clamping jaws or shaft 17 and th are deflected laterally towards each other so as to come in a vertical line and thereby admit of direct inward'pull'being exerted thereon by means of tends to draw the rear ends of the levers 19 together and hold th cam 11 is arranged of the upper clam occupies an approximately vertical carries the clamping jaws at its pivotally mounted at its A shaft or rod 15 is supported at position by means of set screws 16. rod or shaft 17 is supported in the upper clamping clamping comprise are mounted upon the rod e rear ends of the levers 19 a spring 20 which normally e jaws separated. Y The ing jaw, whereas the cam 12 is arranged in t e plane of the lever of the lower clamping jaw. The lower clamping jaw has a projection 21 adapted to form a support for the binder 22 when placed in in the plane of the lever in bearin s forming a part-of'the frame-work position preliminary to the operation of the machine.

The bending blade 23 is supported by means of arms 24 which are secured to a shaft 25 mounted in bearings of the framework. An arm 26 secured to the shaft 25 projects in the path of the cam 13 to be actuated thereby to normally hold the bending blade in proper position for folding the binding strip 22 as indicated in Fig. 2. An antifriction roller 27 applied to the end, of the arm 26 reduces the friction between said arm and the cam 13 to the smallest amount pos-v sible'. An article holder is loosely mounted upon the shaft 25 and comprises a pressure bar 28 and arms 29, the latter being mounted upon the shaft 25. The bending b ade when elevated or in normal position engages with I the article holder and lifts the same clear of the article, but when the bending blade drops out of the way, the article holder 1s drawn downward by means of a spring 30 interposed between it and the main frame-work, thereby bringin the pressure bar 28 in firm engagement wit .the article, whereby it IS retained in proper positlon.

The article support 31 may be of any form and is arranged beneath the pressure bar 28.

of the article holder so as to secure the article 32 when placed in position thereon. In the event of the article being a dish formed of sheet material such as veneer or paper, the folds of the blank resulting from shaping the same are confined between the support 31 and the pressure bar 28, and when the bending blade drops out of the way and the spring 30 comes into lay, the pressure bar is drawn downward with such force as to compress the foldsjand admit of the binder passing read1ly thereover.

The swinging frame 14 carrying the clamping jaws is drawn rearward by means of springs 33 which are interposed between the standards 1 and the members of the swinging frame. An arm 34 projected rearward from the upper portion of the swinging frame is adapted to cooperate with the cam 10 to control the movements of the swinging frame and the proper advance and retraction of the clampin 'aws. The arm 34 is provided with an anti- 'ction roller 35 which makes direct "connection with the cam 10.

' In the operation of the machine, the article 32 is placed upon the support 31 be-' tween the latter and the pressure bar 28 of the article holder after which the machine is started by operating the treadle mechanism to throw the clutch in gear. Preliminary to starting the machine, the binding strip 22 is placed in position between the bending blade 23 and the frontends of the clamping jaws.

- As the drive shaft 3 begins to rotate, a portion of the cam 10 exerts a forward pressure upon the arm 34 and swings the upper end of the frame 14 forward, carrying with it the clamping jaws, and the latter coming in contact with edge portions of the bindingstrip 22 above and below the bending blade 23, j fold said strip about the bending blade, and

after the strip has been bent, the projecting j portion of the cam '10 clears the arm 34 and permits the upper ortion of the frame 14 to be drawn rearwarc, the bent strip held between the clamping jaws being moved rearward and clearing the bending blade. At

this time, the cam 13 clears the arm 26 and permits the bending blade to drop as indicated in 3, said bending blade being moved downward out of the way by gravity as well as by the action of the downward pull of the springs 30 upon the article holder. As the bending blade drops and releases the article holder, the pressure bar 28 thereof grips the article 32 and prevents displacement thereof during the application of the binder thereto. As soon as the bending blade drops out of the way of the clamping jaws, the latter are advanced by the action of the cam 10 which exerts a forward pressure on the arm 34, thereby swinging the uper end of the frame 14 forward with the result that the binder slips upon the projecting edge of the article as indicated in Fig. 3. After the frame 14 advances the clamping jaws to the limit of their forward movement, the cams 11 and 12 come into play and move thereby closing said jaws and setting the binder or clenching the same upon opposite sides of the article. To prevent possible displacement of the binding strip when set, the jaws may formed to indent opposite portions of the binder and cause the same to positively interlock with the article so that the binder cannot be withdrawn or stripped from the article. After the clamping jaws have been pressed together and released, they are separated by the action of the spring 20 and an instant later, the arm 34 is released from forward pressure of the cam 10 and is drawn ,rearward by the action of the springs 33 and when the drive shaft has made a complete 1 revolution, it is automatically thrown out of gear by the shipping of the clutch sleeve 5 and the parts returned to normal position preliminary to a repetition of the operation in the application of the next binding strip.

The opposing portions of the pulley 4 and clutch sleeve 5 are provided with teeth or clutch elements which when in engagement cause the parts to rotate togethen spring 35 mounted upon the shaft 3 and interposed between the clutch sleeve and the proximal standard normally exerts a pressure upon said clutch sleeve to force it outward towards the pulley 4. A cam 36 is formed on the side of the clutch sleeve'facing the pulley 4 and is adapted to be engaged by a stop at the outer end of a pivoted hook 37 to which the the levers 19 of the clamping jaws apart,-

be roughened, fluted or otherwise settlng the binder, and means to admit of the bending blade clearing the binder setting 40 diately after the bending of the binder and i to the application and setting of' upper end of the rod or bar 9 is-connected.

As shown m Fig. 1, the stop at the outer end of the hook 37 is m on agement with thecam 36 and holds the clutc sleeveaway from the ulley, thereby compressing the spring 35,

pon depressing the treadle'7, the hook 37- is, thrown upward at its free end, thereby :releasin the clutch sleeve which is thrown end to project its stop into thepath of the throwing the machine out cam 36, and when the shaft completes its revolution the clutch sleeve is moved inward or away from 'the of gear.
